Application filed August 16, 1912. Serial No. 715,454.

its primary object is to provide simple and.

improved means for casting a hollow slug which possesses advantages oversuch hollow or skeleton slugs as have been produced heretofore, therebeing but one piece located between the mold cap and body to regulatethe length and thickness of the slug to be least and to produce hollowspaces which open into the bottom of the slug, the slugs producedaccording to the present invention enabling single type to be packedagainst them. Also, the means provided by the present invention forproducing such slugs may be properly positioned in the mold withfacility, the core being preferably combined with or formed as apart ofone or both of the liners which serve to gage the spacebetween the moldbody and cap.

To these and other ends, the invention consists in certain improvements,and combinations and arrangements of parts, all as will be hereinaftermore fully-described, the novel features being pointed out particularlyin the claims at the end of the specification. v

In the accompanying drawing,;Figure 1 is a perspective view of alinotypemold as viewed from the front and showing the same fitted with aliner according to the present invention; Fig. 2 represents a frontelevation of the mold, partlyin section; Fig. 3 represents a transversesection through the mold, the liner therein, and showing a line ofmatrices presented to the mold'by the matrix elevator or carrier; Fig; 4represents a horizontal longitudinal section through the moldimmediately below the plane of the mold cap; Fig. 5 is a perspectiveview of the core combined with the liners; Fig. 6 is a perspective viewof a slug of the kind produced by a mold embodying the presentinvention.

Similar parts are designated by the same reference characters in theseveral views.

The present invention is applicable generally to machines for castinglines of type in the form of slugs and is particularly adapted to beused in connectionv with the well known Mergenthaler linotype machines,

it being shownin the present instance as applied to a mold ada ted foruse in connection with such machines, the mold comprismg a mold-body 1which is adapted to be secured asusual to the mold wheel or disk, a moldcap 2, and screws 3 which serve to secure the cap in proper position onthe mold body. In the present invention, a single liner is employed togage the distance between the mold body and cap, such liner embodyingthe end sections 4 and 5, and the liner is reduced in thickness andwidth for a part of its length by cutting away a portion of its upperand lower surfaces and of its front edge to provide the reduced coresection 6, thereby forming a U-shaped cavity when the liner is in placein the mold, said cavity extending in'an unbroken line along the facesof the mold body and cap, the center of said cavity midway between thebody and cap being occupied by the reduced part 6 of the liner. In thepresent instance, such sections 4 and 5 of the liner are adapted to beinterposed between the respective ends cf the mold cap and body, and thedifferent parts of the mold are clamped firmly together by the screws 3.In order to accurately position the different parts of the mold, thescrews 3 are preferably surrounded by bushings 7 which cooperate withthe mold cap and the liners. A dowel 8 is also preferably used to assistthe screws and bushings in positioning the diflerent parts of the moldcorrectly. According to the present invention, the core section 6 isprovided which is-adapted to be so positioned in the mold cavity thatthe metal when introduced into the mold will cover the top and bottomand front edge of the core whereby the core cavity thus produced will becontained wholly within the slug, and the top and bottom faces of theslug will be intact or free from recesses or other depressions, the corechamber being open to the exterior of the slug only at the back thereof.In order to facilitate separation of the cast slug from the core, thelatter is preferably beveled or tapered in transverse section, as shown,and in order to\ stiffen or reinforce the faces of the slug, a suitablenumber of notches 9 areformed in the core and extend rearwardly from thefront edge thereof, these notches being also preferably tapered as shownto facilitate separation of the cast slug from the core. The slug 10which is produced by the aid of a core of this construction has the topand bottom fiat faces 11 and 12 thereof smooth and uninterrupted byrecesses or other depressions, thereby enabling lines of single type tobe packed at either or both sides of the slug, and the core cavity 13 isdivided in a direction longitudinally of the slug by transverse webs 14which connect those portions of the slug at opposite sides of the corechamber, the'slug possessing substantially the strength of.the ordinarysolid slug, although it is lighter in weight and requires the use ofless metal. In the preferred embodiments of the invention, the core iscombined with the liners, as this arrangement facilitates the handlingof the core and insures proper positioning-of the core within the moldcavity. In the present instance, the core is attached to or formed as apart of the end sections 1 and 5 of the liner, and when the liner isplaced in the mold, correct positioning of the core in the mold cavityis insured. To facilitate application and removal of the liner and core,the liner section 1 may be formed with open slots or recesses 15 and 16extending inwardly from the end and adjacent side thereof to receive thedowel 8 and the corresponding bushing 7 and the liner section 5 may beprovided with a slot or recess 17 extending inwardly from one sidethereof to receive the bushing 7 at the corresponding end of the mold,it being only necessary to swing the liner about the dowel 8 as an axisin order to remove and insert these parts, and the screws 3 whentightened serve to secure the parts in proper relation. The elevator orcarrier 18 may serve in the usual way toposition a line of matrices 19before the mold, preparatory to the casting operation, this line ofmatrices closing the front of the mold cavity, as usual, and the metalmay be introduced at the opposite side of the mold by the usual metalpot.

The casting of hollow slugs is desirable when slugs of comparativelylarge size are used, not only for the purpose of diminishing the weightof metal in the slugs, but also to allow the slugs to chill morequickly,

Hollow or skeleton slugs have heretofore been produced in differentways, although the principal'method has been to employ a core which wasplaced adjacent to one side of the mold, and hence, the slug cast'withthat arrangement had recesses or depressions in the top or bottom sidethereof. A slug of that form was objectionable for several reasons, andnotably because it precluded the packing of a line of single typeagainst the recessed side thereof, for the reason that the feet of thetype would enter the recess in the slug. Such objections as were foundto exist with the previous arrangement have been obviated by the presentinvention which enables a slug of improved form to be pro duced, and thehandling and positioning of the core is greatly facilitated.

I claim as my invention 1. In a mold for linotype machines, a core, andliners for positioning the core in the mold cavity and in spacedrelation to the cap and body thereof.

2. In a mold for linotype machines embodying members forming the sidesthereof, and a core having liners connected thereto for supporting it inthe mold cavity in spaced relation to said side-forming members.

3. The combination of a mold for linotype machines, a core, and linersfor positioning the core centrally between the sides of the mold cavity.

4. In a mold for linotype machines having a mold body and cap, linersfor spacing the distance between the body and cap and having a coreconnected thereto and filling a plortion of the mold cavity to form acored s ug.

5. The combination of a mold having a cavity for casting a line of type,and a core having liners cooperative with the ends thereof forpositioning the core intermediate the top and bottom walls of the moldcavity.

6. The-combination of a mold having a cavity for casting a line of type,and a core having liners for positioning it in the mold cavity andextending forwardly from the rear edge thereof, the forward edge of thecore having web-forming notches extending rearwardly from the forwardedge thereof.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
